Cost per authorisation decision

What does it cost to know you are still authorised?

Continuous assurance is not free. But a point-in-time decision, made once on evidence that is already stale, is dearer than it looks once you price the blind spot it leaves behind. Set the classification, choose a model, and let an AI-assist take some of the manual load. The human decision stays human.

Higher classification means more controls and tighter handling: more hours per control.

Authorisation model Point-in-time

One big re-accreditation every 3 years, or a steady continuous cadence.

Share of the manual evidence and drafting work (crosswalks, POA&M, summaries) an assistant takes off the human. The decision stays human.

Cost per authorisation decision

7.5× dearer
Point-in-time Continuous AI-assisted (saved)

What this shows. A point-in-time re-accreditation is one big batch that buys a single decision, so its cost-per-decision is tall and amber. A continuous model spreads a lean, mostly automated effort across many decisions, so each one is cheap and teal. AI-assist bends the manual portion down in both; because continuous is already lean, the saving is a bigger share of a smaller bill.

Evidence age over time

avg 548 days
Point-in-time age Continuous age Stale threshold Blind spot

What this shows. Point-in-time evidence ages in a long ramp: for most of the cycle the certificate asserts a posture that is over a year old, and the red area above the stale line is the blind spot you are carrying. Continuous re-verification keeps evidence young and the blind spot bounded to one cadence.

Illustrative. Synthetic figures, not a costing tool. A deterministic teaching model with hand-authored constants: the picture is identical on every load. The authorisation decision stays human.
